SPECIFICATION forming part of Letters Patent No. 447,038, dated February24, 1891.

Application filed October 11, 1889.

T0 aZZ whom it may concern:

Be it known that I, JOSIAH W. BABCOCK, a citizen of the United States,residing at San Diego, in the county of San Diego and State ofCalifornia, have inven ed certain new and useful Improvements inPositive Shuttle-Motions for Looms; and I do hereby declare thefollowing to be a full, clear, and exact description of the invention,such as will enable others skilled in the art to which it app'ertains tomake and use the same.

My invention relates to that class of shuttle-motions for looms in whichthe shuttle is carried back and forth in a positive manner incontradistinction to being thrown, and in which the shuttle isvadaptedto hold a circular disk bobbin that carries the thread or wire, and isactuated by hollow shuttle-carriers, which are operated intermittentlyin opposite directions by any suitable positively-acting mechanism, andare provided with catches which operate automatically to engage eithercarrier with and to disengage it from the shuttle or shuttle-frame; andmy invention consists in certain improvements in a shuttlemotion of thisclass which will be hereinafter fully described and claimed.

Referring to the accompanying drawings, Figure 1 is a view in sideelevation illustrat- 1ng my invention, and showing the shuttle as beingtransferred from one carrier to the other. Fig. 2 is a similar sideelevation, partly in section. Fig. 3 is a top plan view. Fig. 4 is aplan view of the shuttle, and Fig. 5 is a detail view of the end casingsof the shuttlecarriers and the spring-actuated hooks which engage theends of the shuttle.

The same letters of reference indicate corresponding parts in all thefigures.

Referring to the several parts by letter, it h indicate the hollowshuttle carriers, with which the shuttle is made to alternately engage,and from which it is alternately and automatically disengaged in orderto draw the shuttle from side to side of the shed of the loom, theshuttle-carriers being reciprocated by any suitable well-known mechanismdesigned for that purpose-such, for example, as that shown in Patent No.4045,98? or Patent No. 209,et39. This reciprocating mechanism forms nopart of my invention, and I will Serial No. 326,745. (No model.)

carrier is secured a metal casing a open at its ends. The lower outerend of each casing is formed with a downwardly-inclined guidepiece g,upon which the pointed end of the .shuttle rides as it enters the hollowcarrier h,

thus serving to guide the end of the shuttle into the carrier, as willbe readily seen.

Upon the top of the outer end of the easings are formed lugs f, betweenwhich are pivoted the hooks I). These new and improved hooks are made ofthe form shown, being centrally pivoted at the point e, and the innerend of each hook is'bent down at nearly a right angle toform alocking-pawl B, which passes down through an opening k in the top ofboth the hollow casing and the shuttlecarrier. An upward extension 0 isformed at the rear end of each casing a, and a spiral spring (Z issecured at one end to this extension and at its other end to the hook I)in front of the pivotal point e of the said hook.

The shuttle 'i, which carries the spool, is formed with the pointed ends1', and is recessed at each end on its upper side to form thelocking-shoulders j close to the pointed extremities of the shuttle, asshown.

In operation one end of the shuttle is first inserted in the inner endof one of the hollow carriers h, pressing up the pawl B against thetension of the spiral spring d until the end of this pawl passes overthe shoulder j, when it falls under the pull of the spiral spring, andthus looks the shuttle in the carrier. As the inner ends of the carriersapproach each other at the center of the shed, the outer end of the hookb on the empty carrier will pass over the .outer end of the hook whichis then holding the shuttle in the other carrier, and as the free end ofthe shuttle enters the end of the empty carrier it presses up the pawl Bof the free hook, thus pressing down its outer end on top of the outerend of the hook which is holding the shuttle. The inner end of thislatter hook is thus raised against the tension of its spring d until itspawl B is free from that shouldered end of the shuttle, thus freeing theshuttle from that carrier, while the pawl of the other hook engages withthe shoulderj on the other end of the shuttle. In this manner every timethe sl'iuttle-cn-rriers meet at the center of the shed the shuttle isauto matically transferred from one carrier to the other, and is thuscarried from side to side of the shed.

Having thus described my invention, what I claim, and desire to secureby Letters Patent, is

1. The combination of hollow shuttle-oarriers having apertures 71; intheir upper sides, the centrally-pivoted spring-actuated hooks havinglocking-pawls B formed at the extremities of their rear ends, and ashuttle recessed at the extremities of its free ends to form shouldersj, substantially as set forth.

2. The combination of the hollow shuttlecnrriers having upon their innerends thocas ings a, the hooks b, pivoted at the pointe on the hollowcasings and formed at their rear ends with the locking-pends B, adaptedto project down through openings 7; in the casings and carriers, thespiral springs (Z, and the shuttle recessed at the extremities of itsfree ends to form looking-shoulders j, substantially as set forth.
